2 x 4K Monitor @ 60 Hz with Thunderbolt Dock G2 Output

you are correct... the DP 1.2 hub in the dock that support both DP ports does not have the bandwidth to run 2 4k monitors at 60HZ... you need to obtain an USB-C to DP or HDMI adapter to get the 2nd monitor to also run at 60HZ... the first monitor would be connected to one of the DO connectors

HP sells a USB-C to DP or HDMI adapter that is tested and fully supported

Did you have to make some configuration changes to get this to work? I have a monitor connected to a display port, and another connected to the USB-C port. The display port gets to 4K @ 60 Hz, but the USB-C monitor only displays up to 1080p at 60Hz.

I’m using 2 HP Z27 4K monitors. One is connected to the dock directly to the DP using a DP TO DP cable. The other is connected to the USB-C display port alternative using a USB-C to USB-C cable. Both cables were packaged with the HP monitors.
